Mercury 4.0 Phantom

Mercury 4.0 Phantom

Next Generation CT QA is Here

Now it's easy to perform QA on advanced CT features that fall outside of your routine QA program. Like Automatic Exposure Control. And Iterative Reconstruction. Plus, you can revamp your traditional tests with new metrics that enable robust and quantitative testing.

The Mercury 4.0 Phantom is the latest iteration of the Mercury Phantom. Designed at Duke University, Mercury 4.0 was created to meet the following needs:

  • Performance and effectiveness of Automatic Exposure Control / Tube Current Modulation
  • Evaluation of image quality for Iterative Reconstruction
  • Advanced quantitative metrics that reflect what clinicians see
  • Size-dependent image quality evaluation
Initial Experience with Mercury 4.0 Phantom

Timothy Szczykutowicz, Ph.D., DABR, Medical Physicist at the University of Wisconsin-Madison, explains how his team has used this novel phantom.
